The Algorithm Killers: A True Story of Murder, Data, and the Women the System Failed

By R.M. Cochran

In the decaying heart of Gary, Indiana-a city riddled with abandoned buildings and forgotten dreams-a predator named Darren Deon Vann hunted women the world deemed disposable. Convicted rapist and ex-Marine, Vann strangled his victims and discarded their bodies in the ruins, exploiting a system that failed to protect the vulnerable. But four years before his killing spree claimed its final life, a former journalist named Thomas Hargrove uncovered the chilling truth: an algorithm he designed, fed with decades of FBI homicide data, flagged a cluster of unsolved strangulations in Northwest Indiana. It screamed serial killer. He warned the police. No one listened.

The Algorithm Killers is a riveting true-crime narrative that exposes the deadly intersection of murder, big data, and institutional neglect. Through harrowing reconstructions based on court records, police reports, and survivor testimonies, author R.M. Cochran brings to life the stories of seven daughters-Afrikka Hardy, Teaira Batey, Anith Jones, Kristine Williams, Tracey Martin, Sonya Billingsley, and Tanya Gatlin-who deserved better from a society that turned a blind eye. From Afrikka's final, unanswered FaceTime call to her mother, to Hargrove's desperate pleas ignored amid bureaucratic silence, this book unravels how technology could have saved lives... if only someone had paid attention.
